Applicationjled October 29, 1914. Serial No. 869,211.

To all whom t may concern Be it` known that I, GUs'rAv A. OLSON, citizen of the United States, residing at Albert Lea, in the county of Freeborn and State of Minnesota, have invented certain new and useful Improvements in Stanchions and I do hereby declare Athe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itV appertains to make and use the same. j

My invention has for its object to provide a highly etiicient stanchion for the wellknown purpose of securing stock -in their stalls; and, to this end, it consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view of the improved stanchion in elevation attached in working position within a stall structure; Fig. 2 is a View corresponding to Fig. l, with the exception that the improved stanchion is shown in an open or spread position; some parts being broken away and some of the exposed parts being shown in section; Fig. 3 is a horizontal section taken on the line m3 ma of Fig. 1, on an enlarged scale; Fig. at is a view of the stall structure in side elevation some parts being broken away; Fig. 5 is a fragmentary view, in elevation, of the upper end portion of the improved stanchion, some parts being broken away and some of the exposed parts being shown in section; Fig. 6 is a horizontal section taken on the line m6 m6 of Fig. 5; Fig. 7 is a detail view, partly in plan and partly in horizontal section, taken on the line fc? of Fig. l, on an enlarged scale; Fig. 8 is a detail View, partly in plan and partly in section, taken on the line m8 m8 of Fig. 2,.on an enlarged scale; and Fig. 9 is a detail view, on an enlarged scale, showing the method of connecting the extensible wing bars with their operating links.

The stall structure, as shown, comprises a rectangular frame l, at the manger end of the stall, and stall dividers 2, in the form of bent pipes anchored at their forward ends to the vertical members of theA frame l and at their rear ends to the floor of the stall.

The improved stanchion'comprises a pair of horizontally spaced, upright bars 3, a pair of duplicate foot brackets 4, and cooperating head brackets 5 and 6. As shown, the bars 3 are of channel form with rounded bottoms and arranged with their iianges projecting outward so that said bottoms engage the neck of the animal held. The foot brackets 4L are rigidly secured, one to the lower end of each of the bars 3, and have inwardly and downwardly curved angle eX- tensions. Said angle extensions are overlapped, with their vertical flanges in flat engagement, vone with the other, and pivotally connected by a nut-equipped bolt 7. This bolt 7 afl'ordsa pivot on which the bars 3 swing during the closing and spreading of the stanchion. In each angle extension of the foot brackets 4. is formed a multiplicity of longitudinally spaced perforations, through any alined pair of which may be passed the bolt 7 for securing the bars 3, at their lower ends, in diiferent set adjustments.

The top brackets 5 and 6 are rigidly se cured to the upper ends of the bars 8, eX- tend horizontally toward each other, and, when the stanchon is closed, meet at the vertical center thereof. The inner or free ends of the top brackets 5 and 6 are' bifurcated and have mounted between the respective prongs thereof sliding blocks 5a and 6a, respectively. These sliding blocks are rigidly but adjustably secured for adjustments toward and from each other by nut-equipped bolts 5b and 6b seated in the prongs of the respective blocks n and 61. Said bolts are adapted to be passed through any one of a multiplicity of longitudinally spaced perforations formed in said blocks. Oppositely projecting flanges on the sides of the blocks 5a and 6a engage the lower edges of the prongs of the respective heads 5 and 6 and thereby hold. said blocks against vertical tilting movements Integrally formed with the block frL is an alining finger 8 adapted to enter a socket 9 formed in the block 6a, when the stanchion is closed, and thereby secure said two blocks, and hence the upper ends of the bars 3, against lateral movement in respect to each other. An upwardly projecting lug is integrally formed with each of the blocks 5a and 6a, and integrally formed with the alining linger 8 is an upwardly projecting lock lug l1, Cooperating with this lock lug 11 to hold the stanchion closed and locked around the neck of an animal, is a springpressed lock member 12. This lock member 12 is in the form of a horizontal loop which embraces the lug 10 on the block 6a and is pivotally secured thereto for vertical lifting movement. When the top brackets 5 and are brought together during the closing movement of the stanchion, the lock member 12' is engaged by the lock lug 11, and cammed thereby into a raised position to permit said lock lugv to pass under the lock member 12# and be embraced thereby. l'ntegrally formed'f with the inner end portion of the lock member 12 is an upwardly projecting linger-like extension 13, by which said lock member may be lifted out of engagement with the' lock lug 1:1 to permit thel stanchion to bey spread and release the held animal.

-B'y adjustably connecting the bottom brackets 4f and adjustabl'yr securing the blocks- 5aand 6a' tothe topY brackets 5` and' 6, respectively, theba-rs 3may be readily adjusted,'in parallel arrangement, toward and' from-each other tovarry the openingbetween the said bars to lit the neck ot the anima-l held thereby.

'Ehe improved stanchion is suspended with freedom for oscillatory movement on the vertical axis by a supporting head? 141 and a pair ot hanger brackets 15. This supporting head 14: is intermediately swivel'ed iorv horizontal swinging'- movement to a. dependingstud'- 16, secured to theA top transverse member oi the frame 1. lnte grally formed with the stud: 16 is a pair of oppositel'y proj'ecting'lock detents 17, which extend in the plane of the, frame 1, and the purpose of which will presently appear. The ends of the supporting head 1K1. are bifurcated andl the upper ends of the hanger brackets 15 are pivotall-y secured thereto for horizontal swinging movement towa-rd and from each other. The lower ends of the hanger brackets 15 are secured', one toA each of the lugs 10. Obviously, these hanger brackets 15 permit tree spreadingand closingmovements of the stanchion.

ntegra-lly formed with the upper` end portions of the hanger brackets 15 is a pair ofy inwardly projecting' lock lugs 18, which extend in a plane between the prongs ot the bifucated ends of the supportingv head M and normally above the lock detents 17. During the spreadingV movement of the stanchion, the outward swinginglmovements' of the lower ends of the hanger brackets' 15 carry the lock lugs 1'8 into the detents 17, thereby securing-the stanchion against oscillatory, lmovement and in the plane of the frame 1. Also'v integrally formed with the hangerI bracket 15 is a pair of coperatin-g guide arms 19` and 20, which holdV the said hangerv brackets against lateral twisting* movement, one in respect to the other. rEhe arm 19 is bifurcated to receive, with sliding movement, the arm 20. These arms 19 and 20 are connected by a slot and pin connection 21. A short chain 22, anchored to the lower end of the stanchion by a clevis 23,` secured to the bolt 7, and to the floor in axial alinement with the stud 1G, permits a limited oscillatory movement of the stanchion, but will hold the lower end thereof against any appreciable horizontal swinging movement.

To prevent the animal from poking its head between the uprights of the frame 1 and the stanchion proper, instead' of through` the stanchion,is provided a fencing in the form of a pair ofextensible wings. rllhere is one of these Vextensible wings car.- ried/ by each of the bars 3 and, when.` the stanchion is closed, they are'V folded within said bars, but', when thelstanchion is spread, they extend into the space between the stanchion Vand the uprghts oit the 'frame struct-ure 1. Each of these extensible wings comprises a depending tubular member 2l and an upwardly projecting flat bar member 25. The wing members 24 are pivotally secured at 26 to the upper ends of the bars 3,v and the wing members 25 are pivotally secured at 3. Both members of each wing are flexibly connected by slidably mounting the tree ends of' the members in the free tubular ends ofthe members 24;. lTo permit angular movements of the wing members with re spect to each other, the members 2a are slotted at 23 to receive the members 25. It will also be noted: that the 'free ends of the wing members Q5 are expanded to prevent their lateral' separation from the wing members 2-1' through the slots 28. Stop shoulders 29 on the pivoted ends of the wing` members 2i and 25' engage the bars 3 to limit the outward swinging movement of said members and to prevent the wing mem- 'il bers 25 frein pulling `endwise out off the wing members 24:.

lit-h theupper end of each wing member 241' isintegrally formed an outwardly and upwardly curved extension 30. Lin-ks. 31 connect these extensions 30 with the lower end portions otliehanger brackets 15. The links 31 are connected to the extensions 30 by bayonet joints and to the hanger brackets 15 by pins 32, any one of a multiplicity or' perforations formed in said hanger brackets. Coiled springs 33, mounted. in the links 31, engagetheextensions 3,0 and yieldingly press the wing members 2e into the channels of the bars 3L The purpose of adjustably connecting` the links 31 to the hanger brackets 15 is to vary their operative length, to compensate'vfor the adjustment of the blocks 5a and 6al with respect to the heads and 6".

27 to thel lower ends of' the bars adapted to be passed through f By reference to Figs. l and 2 itv will be noted that the lower end portions of the hanger brackets l5 are curved inwardly and downwardly, and, by forcing a fork handle or other tool between the lock finger 13 and the hanger bracket l5 which is connected to the bracket 5, said finger will be cammed away from said hanger bracket and thereby lift the lock member 12 out of engagement with the lock lug l1. i
